Résumé

The LIFE-ADVICLIM project “aimed to improve local management of vineyards in the face of climate change. It has developed tools to measure and model both contributions to climate change and the impact of climate change. It has built on these to help identify the best responses to mitigate and adapt to the impact of climate change in vineyards". In order to achieve these objectives, several Technical Actions (field experiments and modelling) have been set up to develop operational tools at vineyard scale, combining a model for adapting wine-growing practices to climate change with greenhouse gas calculation model. The general approach and structure of the LIFE-ADVICLIM project are presented in Figure 2. The first action A1 was the employment of an experimental protocol, designed to provide key inputs on temporal and spatial variability in viticulture. The measurement networks were installed in each pilot site, allowing the acquisition of climatic and agronomic data. The fine-scale agroclimatic models, derived from measuring data, made it possible to model and evaluate the spatial variability in local climate. With a better understanding of the local climate and grapevine performance, generated results were linked with regional climate change projections. Coupling bottom-up with top-down models allowed the construction of higher resolution outputs of current and future agro-climatic potentials (RCP4.5 and RCP8.5 by 2031-2050 and 2081-2100). The integration of local climate variability (bioclimatic indices and phenological modelling) into regionalized climate change simulations provided an assessment of the impacts of climate change for European viticulture at the vineyard scale (voir A1_deliverable). The data generated from this Action A1 has been used in Actions B1 and B2. In Action B1, a multi-agent model (SEVE) was developed to assess the effect of climate change, and associated increased climate variability, on grapevine growth and on vineyard management practices. The objective of this model was to define climate change adaptation scenarios, based on climatic spatial variability and winegrowing practices. With an important involvement of local winegrowers and their inputs, this multi-criteria modelling approach was applied to each pilot site, which allowed adaptation scenarios to be defined on the scale of the vineyard. The objective of Action B2 was to calculate pilot site carbon footprints according to the different climate change adaptation scenarios identified in Action B1. Carbon footprints has been calculated, according to the winegrower's cultivation practices, on representative test plots for each pilot site. This scale provided a detailed diagnosis that allowed to emit recommendations for climate change mitigation. Actions B1 and B2 are linked in order to provide winegrowers with a manual on adapting and mitigating to climate change. Although there are many management tools or options that hold great potential for winegrowers, there is yet little guidance on how practices should be undertaken at different temporal and spatial scales in response to climate change. Action B3 monitored the results of B1 and B2 on several plots representative of each pilot site. Action B3's objective was to recommend effective adaptation and mitigation techniques to each pilot site, thus generating knowledge and promoting communication between policy-makers and decision-takers. This action was delivered in three formats: the VIDAC web platform (Action B4), published material (in the form of pilot site-specific leaflets) and a Story Map (a pedagogical tool presenting each action of the project in the form of interactive map). Finally, Action B4 is the direct communication of results to winegrowers, seeking to influence their management and decision making. The VIDAC platform was therefore created, which has a user-friendly interface, allowing to visualize the collected field data and information relevant to ongoing decision making. Action C, separated into two sub-actions, was intended to monitor the impact of actions in this project. Action C1, estimating the environmental impact of the project’s findings, followed a two-step approach: a general environmental assessment for each site, followed by a specific environmental assessment based on the adaptation scenarios defined in Actions B. The action plan of the C1 project has been restructured. It has been difficult to assess the impact of individual adaptation measures on the environment in quantifiable terms. Direct implementation of the results of Action B in plots representative of pilot sites is only possible in the long term. Action C2 sought to assess the impact of the adaptation responses generated by the project from an economic point of view. The costs of viticultural practices for representative plots in each pilot site were be estimated for the current situation and for future climate change scenarios. It is important to note that all the actions of ADVICLIM have been carried out in a close relationship with the winegrowers of each study region, representative of European viticulture. Indeed, all studied vineyard plots in pilot sites belong to local winegrowers, except in England where the pilot site is owned by the partner (Plumpton College). Therefore, firstly, the different viticultural practices and strategies implemented in the Technical Actions were defined with and by winegrowers through participatory surveys and workshops. From here, the results and the various recommendations were discussed with the concerned grape and wine professionals in order to valid project outputs before diffusion. The LIFE-ADVICLIM project therefore placed a strong emphasis on working closely with winegrowers.
